test-driven-development

The test-driven development process requires writing failing tests before implementation, then writing minimal code to pass them, and finally refactoring to ensure code quality and prevent regressions.

To apply the Red-Green-Refactor cycle, first write a failing test for a new feature, implement the minimal code required to make it pass, then refactor the code while ensuring all tests remain green.

Yes, test-driven development prevents code regressions by enforcing a rigorous development process where predefined tests must remain green before and after you refactor the underlying implementation.

You should use a test-first development methodology when developing new features like user authentication, ensuring robust software by mandating failing tests are written before any implementation code exists.

A limitation of enforcing test-driven development is that it mandates writing failing tests before any implementation code, which may slow down initial agile development velocity for rapid prototyping.
